The future may provide a microplastics solution in the form of specific bacterial combinations where, in the same way as we combine cytotoxic drugs to fight specific forms of cancer, plastic-digesting combinations can be used to degrade different types of polyethylene. Bacteria grow as colonies on solid media. Form it pertains to the shape of the colony such as filamentous, circular, and the likes. In the laboratory, naturally-occurring B. subtilis enzymes were able to normalize pH, reduce COD by over 87%, lower TSS by over 90%, and remove nearly 50% of chloride. J. Agric .
